shandong fuan da truck parts manufacture co., ltd wheel edges reducer use quality problem analysis
users in the use of wheel edges in the process of gear reducer, often appear round bottom edge planetary gear wearing, heat, the phenomenon such as abnormal sound, comprehensive analysis, draw the following reasons:
1: product machining quality problems.
round reduce the processing precision is to guarantee the main five planets between the sun and the wheel when center position of the degree requirements. if assurance not will appear between planetary gear, and the sun between stress and wheel bite unfair. damage caused by gear. or a gear stress caused this big gear wheel wear of the side at the bottom. to ensure the accuracy of the wheel reduction processing. with high precision cnc processing must center and improve and perfect the quality management. ordinary machine tool can't processing of qualified wheel decreases.
2: assembly quality problems.
assembly quality problem is mainly to the assembly parts quality control, the planet shaft if materials do not comply with requirements or heat treatment is unqualified hardness is not enough, can cause serious loss planet shaft grinding round failure, cause the damage of bearing and gear. and needle bearings and gear, the choice is bad will appear afore-mentioned problems. as long as there the above situation, all is the quality problems.
3: oil quality, and how little oil leakage is also causes the wheel or reduce the cause of damage.
4: jerry.
some round in process reducing, reducing the circle diameter and the thickness of the plate and make the enough strength reduction is also the cause of damage.
